Provided is a charging cleaning member that can efficiently clean contaminants on the surface of a charging roller and maintain the cleaning performance for a long period of time, and can uniformly charge the surface of an image carrier. A charging device including a charging roller is provided. The charging device includes a charging roller a that is rotatably supported and charges the surface of the image carrier 11 by applying a voltage from the outside, and a charging cleaning member 14b that cleans the surface of the charging roller 14a. The charging roller 14a has a resistance adjusting layer 142 made of a resin composition formed on the outer periphery of a metal core 141, has a hardness of 45 degrees (JIS-D) or more, and the charging cleaning member 14b includes at least the charging roller 14a. Are made of a resin foam having an open-cell structure with a density of 5 to 15 kg / m 3 and a tensile strength of 1.7 ± 0.5 kg / cm 2 . [Selection] Figure 2 |
